Application filed August 27, 1906. Serial No. 832,224. Y

Ta'all whom itmuy concern Be it known that I, HYMAN E. MARKLE, citizen of the United States, residing at Nashville, in the county of Davidson and State of Tennessee, have invented certain new. and useful Improvements in Sound Reproducing Machines, of which the following is a specification.

My invention relates to sound reproducing machines generally, but more particularly .to the multiplex cylinder machine whereinare employed a series of cylinders with means to bring the cylinders succes- 'sivelyinto operative relation with the resame. Figs. 3 and .view through producer, and it is the object of. my invention to improve and simplify this type of machine; and with this and minor objects in view, my invention consists of the parts and combination of parts as will be hereinafter pointed out and claimed. In the drawings, Figure 1 is a side elevation of a phonograph embodying my invention..- Fig. 2 is a front elevation of the the.castings constituting the gear housing.

Figs. 5, 6, 7 and8 are detail views. Fig, 9. is a top plan view of the carriage, Fig. 10 the arch bar which is a top and side view of supports the front of the carriage, the pawl being shown in position for assembling with said bar, Fig. 11 is a detail elevation ofthe trip mechanism, Fig. 12 is a detail sectional one of the arms of the star wheel and cylinder, Fig. 13 is a similar view of opposite star wheel and one of its hinged sections.

1 designates the hrse or support of the machine having an opening on each side of which are positioned depending arms 2 proided with suitable journal. bearings 3 in which are journaled the star wheels 4 and 5.

6 are. shafts journaled in the outer ends of .the arms of the star wheel 4 on which are keyed pinions 7. 3 are record holding cylinderssecured on the shafts 6. The arms of the wheel are each provided with hinged sections 9, the outer end of each of which is provided with a center pinlO adapted to support one end of the cylinders 8.

11 is a locking lever or key pivoted to the wheel 5 by means of the pivot 12. The outer end of this lever or key 11 is provided with a set screw 13 adapted to bear against the said section is sup- 4 are side elevations of .centering pin 10, held against the cylinder 8, The set screw enables one to adjust the pressure with which the centering pin bears against the cylinder 8. When ever it is desired to place a record on the cylinder, the lever or key 11 is swung on its pivot parallel with the wheel 5 whereupon the section 9 is free to swing on its hinge away from the wheel, thus freeing the end of the cylinder 8 adjacent to the wheel 5, whereupon the record may be placed upon or removed from its cylinder. As soon as a record is placed upon a cylinder, the section 9 is thrown up and the locking lever or key swung upward on its pivot into the position shown in Fig. 13 and the proper adjustment of the bearing pin 10 against the end of the cylinder is regulated by means of the set screw 13 on said leverll.

14 and 15 are castings constituting a suitable housing for a train of gear wheels. The casting 15 is provided with journal bearings 16, tubular project-ions 17 and brackets 18 and 19 on opposite ends and lugs 20, while the casting 14 is provided with screw openings with which the projections 17 register.

21 are screws holding the castings together by passing through the openings in-casting 14 and engaging suitable screw threads in said projections or lugs 17. The lugs bear against the ends of the casting 14.

22, 23, 24, 25 and 26 are gear wheels suitably journaled in the housing formedof the castings 4 and 5. On the shaft 27 of the gear wheel 22 is keyed a suitable band or other power wheel.

28 is. a pinion keyed to the shaft 31 of the gear wheel 25, said shaft being journaled in the standard 29.

30 is a pinion keyed to the shaft 31 and is adapted to engage the pinions '7 of the star wheel whereby the cylinders are revolved.

The gear wheel 25 mesheswith the gear wheel 26.

32 is the return or repeating bar having a worm of the desired pitch formed thereon. the other end of the bar'32 being journaled in the standard 33. The standard 33 is more clearly shown in Figs. 2and 11 from which it will be seen that it is provided with an arm 34 carrying a U-shaped lug35 on its outer end. A carriage slide bar 36is supported at the front of the machinein the lug 35 of the standard 33 and inthe lug 19 of the casting 15 in which it is held by means of suitable set screws.

The carriage 36, for carrying the reproducing means, (not shown) is supported in the front by means of the arched bar 37 having lugs 38 by means of which it is secured to the carriage. The outer end of the bar 37 is provided with a cross piece 39 (see Fig. 10) having a depending foot 40 adapted to slide on the slide bar 36 as clearly shown in Fig. 1.

41 is a pawl, the upper end 42 of which is outwardly deflected, the lower end of the pawl depending, normally, below the top of the slide bar 36, as shown in Fig. 1. This pawl is pivoted to the cross piece 39 between lugs. 43. A coiled or other suitable spring 45 is secured between the cross piece 39 and the end 42 of the pawl 41 as shown in Fig. 1. The tendency of the spring 45 to throw the lower end of the pawl in toward the carriage is normally resisted by the slide bar 36 46 is an arm provided with a trip 47 at its outer end, said arm having an integral lug 48, by means of which it is secured to the carriage, the said arm projecting in advance of the carriage, as clearly shown in Fig. 2.

49 is an arm integral with and depending forwardly from the arm 46, the end of which is provided with fingers 50 and 51, to be hereinafter referred to.

52 is a rod, one end of which is fixed in the lug 18 of the castin 15, the other end being suitably supporte The arched bar 53 is Slidably mounted on the rod 52 at one end and is secured at'its other end to the rear of the carriage, thus coacting with the arched bar 37 to support the carriage 36. An arm 54 (shown partially in dotted lines in Fig. 1) is connected to the outer end of the arched bar 53 and its inner end carries a Worm feeding nut, which engages the feed screw 55, whereby the carriage is propelled to traverse a record. The feed screw is keyed to the gear wheel 24.

56 is a bell crank lever pivoted at 57 to the arm 54; the other end of the lever 56 is provided with a yoke 58 (shown in dotted lines in Fig. 1) which is adapted to engage a boss 59 formed on the ends of the arms of the star wheels 4 and 5 whereby said wheels are held against movement while a record is being reproduced.

60 is a rod extending from a pivoted end of the bell crank lever, which has a sliding engagement with a rod 61 fixed to the arched bar 53, so that. when the front end of the carriage is raised, the rod 61 forces the rod 50 upward, thus swinging the bell crank lever on its pivot and disengaging the yoked end from the arm ofthe star wheel, whereupon the wheel is free to be revolved to ad- Vance another record into operative posit1on.

62 is a bracket depending from the support 1 provided with an arm 63.

64 is a ratchet wheel suitably journaled on the lower end of the bracket and provided with bevel gear teeth (indicatedby a dotted circle in Fig. 2) on its rear side, which mesh with a bevel gear wheel 65 keyed to the shaft of the star wheel 5.

66 is a lever pivoted at 67 to the arm 63; 68 is a pawl pivo-tally secured to the lower end of the lever 66 and held at a right angle thereto by means of a coiled spring 69 in which position it is in engagement with the ratchet wheel 64. The lever 66 is offset intermediate its upper end and pivot as at- 70 which permits the end of the arm 46 to pass the lever without engaging it as the carriage progresses in the reproduction of a record, as shown in full lines in Fig. 11. The path of the finger 50 is below the top of the bar 32 in the forward movement of the carriage. The slide bar 36 is provided with a trip 71 which is adapted to push the pawl 41 from the top of said bar after the carriage has returned to starting position, said trip having a cam-like face.

The operation of the machine is as follows: Records having been placed upon the cylinders 8, and the star wheels locked to the repeating bar 32 engages the finger 50 of the arm 49 and continuing in its movement, thereby elevates the arm and throu h it the carriage until the pawl 41, under t e influence of its spring, snaps over the slide bar 36 and its lower end rests upon said bar holding the carriage in its elevated position, in which position the trip 47 on the bar 46 is above the offset in the lever 66 and the finger 51 is in engagement with the repeating bar 32. The elevation of the front end of the carriage causes it to swing at its rear end on the rod 52, thereby freeing the feeding nut from the feed screw 55 and at the same time through the rod 61 and arm 60, freeing the yoked end of the bell crank lever 56 from engagement with the star wheels,

thus leaving the wheels free to be revolved.

throws the lever over on its pivot 67 which.

movement, through the pawl 68, revolves the ratchet wheel-64, the bevel gear 65 and the shaft of the star wheel 5, thereby revolving both star wheels and thus advancing a new recordinto proper position for reproducstruction, withoutdeparting from the spirit of the invention, hence, I would have it understood that I do not limit myself to the exact details shown. I
